I have the C-3 and added the SRC unit to it a little over 2 years ago. The unit failed recently and it was over
the stated warranty period. They told me to ship it to them and they inspected it and are sending me a
replacement even though the unit is over warranty. I had a liner problem as noted earlier in this thread and
they sent me the S-2 liner for free............this is the second positive outcome with them......customer
service at Schuberth rocks!
